[Project] Make nf-core create more customisable

[ewels]

The nf-core template is central to the community and is increasingly important, both as the community grows (more nf-core pipelines) and as the tooling is used for non nf-core pipelines more and more.

There are a few specific tasks to do here, this issue is to track the overall progress.

@adamrtalbot created this minimal viable nf-core pipeline, which could be a good target for this rewrite with all flags disabled: https://github.com/adamrtalbot/nf-stem/

Got pointed towards this issue by @edmundmiller, definitely excited about these additional customization features. #1961 in particular has been on my feature wishlist for some time.

@adamrtalbot Just took a look at your nf-stem project. It looks like a great approach! Will probably use your version the next time I do a project that calls for a minimal template.

Thanks @kenibrewer, your version was a big inspiration.

For what it's worth, I think we can go further now. More streamlined than ever!
